The problem of strange reflection - does not work

Question

please help me understand what is happening here and should this work like that? I have a general list of objects from CMS:

For example List<MyCMS.Articles.Article> myArticles = articles.All;

Later, I list the contents of the list in JSON format (for the list of CI UI, a table).

Now one entry will include:

article.Title
article.Alias
article.Guid
article.Description
+
article.SeoProperties.TitleOverride
article.SeoProperties.H1Tag
article.StateProperties.IsActive
article.StateProperties.Channels

etc...

since you can see that the Article object has an additional class property - with common properties (used for other types of objects in CMS)

I also use a filter class that performs some filter operations with LINQ in the collection to return only articles in a specific channel to me, for example ...

, , JSON - "", , - , , , "" ( ) .. - DataContractJsonSerializer...

, JSON... , , , [DataMember (IsRequired = false, EmitDefaultValue = false)]... - - - ( !!) , = set value to "null" - null - - ... ?

void Page_Load() {
        MyCms.Content.Games games = new MyCms.Content.Games();
        List<MyCms.Content.Games.Game> allGames = games.All;

        MyCms.Content.Games games2 = new MyCms.Content.Games();
        List<MyCms.Content.Games.Game> allGamesOther = games2.All;

        Response.Write("Total games: " + allGames.Count + "<br />");

        //This is our fields stripper - with result assigned to a new list
        List<MyCms.Content.Games.Game> completelyUnrelatedOtherIsolated_but_notSureList = RemoveUnusedFields(allGamesOther);

        List<MyCms.Content.Games.Game> gamesFiltered = allGames.Where(g=>g.GamingProperties.Software=="89070ef9-e115-4907-9996-6421e6013993").ToList();

        Response.Write("Filtered games: " + gamesFiltered.Count + "<br /><br />");

    }

    private List<MyCms.Content.Games.Game> RemoveUnusedFields(List<MyCms.Content.Games.Game> games)
    {
        List<MyCms.Content.Games.Game> result = new List<MyCms.Content.Games.Game>();

        if (games != null && games.Count > 0)
        {
            //Retrieve a list of current object properties
            List<string> myContentProperties = MyCms.Utils.GetContentProperties(games[0]);

            MyCms.PropertyReflector pF = new MyCms.PropertyReflector();

            foreach (MyCms.Content.Games.Game contentItem in games)
            {
                MyCms.Content.Games.Game myNewGame = (MyCms.Content.Games.Game)contentItem.Clone();
                myNewGame.Images = "wtf!"; //just to be sure we do set this stuff not only null

                pF.SetValue(myNewGame, "GamingProperties.Software", ""); //set one property to null for testing

                result.Add(myNewGame);

            }
        }

    return result;
